Unfortunately gold does not provide the flexibility that ld offer, You can see
the same behavior on the other platforms.

Yes I do and it does not.
.got and .got.plt must be set properly in linker srcript to get it work
otherwise a segmentation fault will be produced. I can see the same behavior on
different platform "x86_64".
